The Central Cooling Plant with Optimization (CCO) application is designed to maximize the chiller plant’s operating efficiency. This application:

  • when enabled, maintains at least one device On to maintain the minimum (or base) load

  • maximizes the plant efficiency by choosing the most efficient device (or combination of devices) available

  • minimizes the total chiller starts

  • if configured, attempts to balance run times and start counts for the chillers

This application determines the combination of chillers to meet the required load, and turns the appropriate devices on and/or off in an orderly manner to arrive at the desired combination. The selected combination produces the largest adjusted Coefficient of Performance (COP). Efficiencies are calculated based on the individual device’s COPs, percent load, required capacity, and rated flow.

This section of the Help describes the system selection options of the Central Cooling Plant with Optimization application, and lists the modules that get populated in the application as a result of the selections. Refer to the Johnson Controls Central Plant Optimization™ 10 Application Note (LIT-12011575) for more application level information on the Central Cooling Plant with Optimization application.

Important: Once system selection is complete, the Chiller Selector, Pump Selector, Cooling Tower Selector and Heat Exchanger Selector modules require further configuration. Refer to the Johnson Controls Central Plant Optimization™ 10 Application Note (LIT-12011575) for information on configuring these modules and for more application level information.
